The application discloses a 3D printing ocular prosthesis platform, which is prepared through the following steps: S1, designing the shape of the ocular prosthesis platform and dividing the shape into regions; S2, selecting a porous structure for the ocular prosthesis platform in each region and determining the voxel size according to the connecting point parameters of the selected porous structure; S3, voxelizing and fitting each region to form a voxelized interface; S4, filling the porous structure selected in step S2 into each corresponding region to complete the modeling of the porous structure in each region; S5, connecting the connecting points on adjacent voxelized interfaces to each other and converting the connecting lines into solid rod models to complete the modeling of the interfaces; S6, merging the models obtained in steps S4 and S5 to obtain a final model of the ocular prosthesis platform; S7, 3D printing to obtain a bioceramic blank; and S8, high-temperature sintering of the blank to obtain a 3D printed ocular prosthesis platform after porcelain forming. The application can obtain a new 3D printed ocular prosthesis platform, which provides technical support for ocular prosthesis repair.

The utility model discloses a kind of connecting structure of HDPE double-wall corrugated pipe and concrete pipe well, including the corrugated pipe in the reserved interface of concrete pipe well, rubber sealing ring, PE flexible pipe being located at the outer periphery of rubber sealing ring and being filled with mortar layer of PE flexible pipe, which is sleeved on the corrugated pipe.The connecting structure of the utility model is constructed, rubber sealing ring is sleeved on the corresponding place of corrugated pipe, and the section of corrugated pipe is inserted into the reserved interface of concrete pipe well, the sealing property of PE flexible pipe is tested by pressurization, vacuum is extracted after completion, and it is placed in the reserved interface, and cement mortar is injected through the feed inlet of PE flexible pipe to form mortar layer.The connecting structure of the utility model sets up the grouting PE flexible pipe between the reserved interface and corrugated pipe, utilizes grouting pressure to seal the gap between PE flexible pipe and reserved interface, plays waterproof effect, realizes rigid pipe well and the rigid-flexible transition between HDPE pipe, avoids pavement cracking, roadbed settlement and other diseases.
